The vitamin crystallises from MeOH or water/EtOH, dry it in air, then dry it further for several hours at 110o or in high vacuum at 120o. It forms yellow crystals from EtOH/Me2CO/H2O (2:1:1). It has also been purified by passing (0.5g) through a Kieselgel column (30 x 5cm) with EtOAc/MeOH/H2O (100:20:15), and after 750mL have passed through, the yellow fraction of 250mL gives the glycoside (0.3g) on evaporation.
